US Patent 11318048 Methods and systems for large spot retinal laser treatment

In some embodiments, a system for providing a therapeutic treatment to a patient's eye includes a treatment beam source configured to transmit a treatment beam along a treatment beam path. The system further includes a processor coupled to the treatment beam source, the processor being configured to direct the treatment beam onto retinal tissue of the patient's eye and deliver a series of short duration pulses from the treatment beam onto the retinal tissue at a first treatment spot to treat the retinal tissue. In some embodiments, a pre-treatment evaluation method using electroretinography (ERG) data may be used to predict effects of treatment beams at different power values and to determine optimal power values.
